Lawrence J. Checkin

Lawrence J. Cheskin, MD, FACP, FTOS is Associate Professor, Health, Behavior & Society at Johns Hopkins Bloomberg School of Public Health, with appointments in  Medicine (GI); International Health (Human Nutrition), and Public Health Studies. He directs the Johns Hopkins Weight Management Center, a multidisciplinary clinical research and treatment program that he founded in 1990. He is also Associate Director of the Global Obesity Prevention Center at Johns Hopkins, and directs its Pilot Studies Core, which evaluates timely, systems-focused proposals worldwide to study such areas as school policies and the built environment’s effect on factors relevant to preventing childhood obesity.

Dr. Cheskin’s career has been dedicated to research, education, and program building in the service of combatting obesity, through both treatment and prevention. His work is at the intersection of public health and clinical medicine: it applies knowledge gained through rigorous clinical investigation, for example through the multi-center Look AHEAD trial he has played a key role in since its inception, to the community and beyond. His work has impacted the problem of obesity through innovative treatment paradigms disseminated through practice (as modeled by the Johns Hopkins Weight Management Center); through application of new treatment paradigms in community-based participatory research, particularly among the underserved in Baltimore, Maryland; and through teaching and mentoring of the next generation of public health and clinical scholars dedicated to obesity.

Most recently, he is studying obesity progression, costs, and treatment using Markov micro-simulation modeling; using mHealth as a tool to enhance obesity treatment; and, through a rigorous multimodal clinical trial, testing the hypothesis that obesity is treatable, and weight control can be sustained in a vulnerable urban minority population when a comprehensive approach is offered which partners with resources in the community.

He has over 150 peer-reviewed journal publications, and has written 7 books.
